[PK 77 911]

I have had the injectors cleaned 3 times since the rebuild which now has 5000km on it. Each time after the injectors have been cleaned it runs perfectly, smooth without a stumble or a miss right from time I let the clutch out. Within about 15 to 20 minutes it starts to stumble, most noticeably off the line. Passengers even notice it.

It did not do this before the rebuild but it needed A rebuild so it did not run that great anyways. The car sat for a wile prior to the rebuild in moisture so the tank could have rusted. I have since had the tank completely cleaned resulting in a clean fuel filter.

It runs okay when driving, just okay, not great. I notice because I am in tune with how the car feels when it is running well. It progressively gets worse until I clean the injectors again.

My mechanic cleans the injectors. It is a preassurised fluid tool. It seems to work for a while.

It is frustrating and thank you all for your comments and advice so far.
